LEGO Challenge Cards are the perfect activity for STEM Centers, for early finishers, or to challenge your advanced students.
This pack includes 35 challenge cards including 6 Holiday cards. These cards can be added to the center during that special time of year or left in all year for a little holiday fun year round (that's what I do!)!
